Initially the hook looked like
rtx
ix86_gen_scratch_sse_rtx (machine_mode mode)
{
if (TARGET_SSE)
return gen_rtx_REG (mode, (TARGET_64BIT
? LAST_REX_SSE_REG
: LAST_SSE_REG));
else
return gen_reg_rtx (mode);
}
on x86, but then PR104704 changed it to the same definition as the default
hook. So I think it is fine to remove it.
